Neural and neuro-fuzzy models are powerful nonlinear modelling tools. Different structures, with different properties, are widely used to capture static or dynamical nonlinear mappings. Static (non-recurrent) models share a common structure: a nonlinear stage, followed by a linear mapping. In this paper, the separability of linear and nonlinear parameters is exploited for completely supervised ...

The modelling and simulation play a very important role in the industry where it can help with the description of the system and the choice of the optimal control strategy. This contribution is focused on the modelling and simulation procedure which usually precedes the design of the controller. The mathematical model is derived with the use of material balance and produces nonlinear Ordinary D...

There are numerous sources of vibration in an industrial environment: in processes such as pile driving and blasting; rotating and reciprocating machinery such as engines, Compressors, and motors; transportation vehicles such as trucks, train and aircraft; the flow of fluids; and many others. Vibration absorption is a method of adding a tuned spring-mass absorber to a system to create anti-reso...

In this article, we address the problem of determining the minimal precision on the inputs and on the intermediary results of a program containing floating-point computations in order to ensure a desired accuracy on the outputs. The first originality of our approach is to combine a forward and a backward static analysis, done by abstract interpretation. The backward analysis computes the minima...

This paper shows a new design and prototyping method for pneumatic rubber actuators. The method enables us to design pneumatic rubber actuators optimally and efficiently based on static analysis using non-linear finite element method, in which geometrical and material non-linearity are considered and also enables us to prototype them rapidly and efficiently by a CAD/CAM based rubber moulding pr...

Objective: To determine the effect of T loop spring position and activation on moment to force ratio. Materials and methods: Study conducted in two parts: (1) By using loop software by Halazonetis. Parameters studied were later on evaluated using FEM. Material properties along with the cross-sectional parameters being the same as in FEM, (2) using FEM, a large deflection nonlinear static analys...
